order that the electrolyte forced within the trap c during the presence of pressure upon valve to move it to the left to reestablish communication between the pipes (Z and l1., permitting the electrolyte to fall back within the hollow electrode structures.

Inasmuch as both broad sides of each hollow electrode structure are preferably similar in construction and function, there is no material electrolytic action between Ithe saine, and in order that the interior surfaces or portions of these broad sides may within the hollow electrode structures, take part in electrolytic action, I supply a complemental electrode element g within each hollow electrode structure. Thus thel broad sides of each hollow electrode structure constitutes one electrode, which sides cooperate with the complemental electrode g interposed therebetween and with the electrolyte surrounding the complemental electrode g in causing electrolytic action on surfaces or portions exposed to the electrolyte within the hollow electrode structure.

I have rot deemedfit essential to describe materials that enter into electrodes ZJ and g, as it will be well known to those skilled in the art how to select and construct these elements.

It is obvious that the outer electrodes b may be formed each in two parts,` for example two halves, whose meeting laces are T/ertical and in the same plane with the axes of the sleeves m, 'these meeting fares, which are of storage battery metallic read, being burned together in accordance with well known storage battery practice after the inner electrode has been disposed therein and the stem 7c or Z has been passed through 'the sleeve m which is positioned in recesses in halves of the end wall through which such stem projects. rIhe stem, after having been projected through such sleeve, is burned to the outer electrode adjacent to the outer electrode through which such stem passes. No insulating and supporting pieces are illustrated as holding the inner elec-J trodes in position, since the stems le Z may be relied upon for this purpose, and particularly are the supporting and dis' omitted .trom the drawings` inasmuch as they would tend to render ol ,cure the essen-- tial features of the invention, but it is of course understood that. they may be snpplied if desired. Separating devices and snpporting devices are so well known in storage battery practice that their use in this strnclure, somewhat diagrannnatically illustrated in the drawing, will be well unllerslood hy those skilled in the art.

I have indicated a eolulnctine,` link Z', preterably of lead, which electrically unites the left-hand electrode and the right-hand electrode 5,-and another such link Z, which unites the left-hand electrode o with the righthand electrode g. These conducting links Zr and Z pass through insulating sleeves m. in the alls of the electrodes the llt hctwecn the insulating sleeves lmy and the links Z: andvZ being sutlicienl'ly tightto prevent pressure from forcing electrolyte through the sleeves.

ance pieces If desired, some suitable means may he ber portions of the in-lets c for the pur-pose.v

This feature of my invention is of particular importance in view of the fact that the active material entering into the construction of the positive and negative electrodes present differing degrees of permeability to the flow of electrolyte therethrough.

lVhile I have shown hollow electrodes of oblong shape, I do not wish to be limited to such a construction in all embodimentsv of the invention. In my copcnding applica.- tion Serial No. 505,571 tiled July 2,1909 I have disclosed equipment having some features in common with the equipment herein disclosed. f

It is very obvious that many changes may be made in the form' o i the invention herein shown and particularly described, without departing from the spirit of the invention, and I do not, therefore, wish to be limited to the precise construction shown, but` Having thus described my invention, I

claim as new and desire to secure byIictters Patent the following:we

l. A storage battery includinga pluralilir of hollow electrodes, each containing ele-c trolytc and a eoinplemental electrode,-eaffh hollow electrode being directly connected with an inner electrode inclosed b v another hollow electrode, and means for forcing the electrolyte through the pores of the active material Aof the hollow electrodes.

A storage battery including a hollow electrode structuresubject to the action of an electrolyte, a container for said hollow electrode structure., a complementmy electrede, means operating to effect intermittent forced circulation of said electrolyte through the pores of the active material and occasioning the passage of electrolyte from the container to the hollow electrode, and means operating to prevent the return passage of electrolyte from the hollow electrode strueture to the container when circulation of the electrolyte is being forced and permitting the passage-of the `electrolyte from the container tothe hollow electrode structure when circulation of the electrolyte is not being forced.

3. A storagebattery including a plurality of hollow electrodes7 each containing an electrolyte and a complemental electrode, each hollow electrode being directly connected with an inner electrode inclosed Aby another' hollow electrode, and a circulating system for forcing the electrolyte through the pores of the active material of the hollow electrodes,'said circulating system including the hollow' electrodes.

Ell

-. 4. A storage battery including a hollow* electrode structure subject to the action of an' electrolyte, a container' for said hollow electrode structure, a complementary electrode, means operating to effect intermittent forced circulation of said electrolyte through the pores of the active material and occa 'circulation of the electrolyte is being forced and permitting the return of the discharged electrolyte to the hollow electrode structure when circulation of the electrolyte is not being forced.

In witness whereof, l hereunto subscribe my name this 29th day of June A. D., 1909.
